The Linux Kernel: Drivers

Filed under
Linux

Drivers are small programs that enable the kernel to communicate and handle hardware or protocols (rules and standards). Without a driver, the kernel does not know how to communicate with the hardware or handle protocols (the kernel actually hands the commands to the BIOS and the BIOS passes them on the the hardware). The Linux Kernel source code contains many drivers (in the form of source code) in the drivers folder. Each folder within the drivers folder will be explained. When configuring and compiling the kernel, it helps to understand the drivers. Otherwise, a user may add drivers to the kernel that they do not need or leave out important drivers. The driver source code usually includes a commented line that states the purpose of the driver. For example, the source code for the tc driver has a single commented line that says the driver is for TURBOchannel buses. Because of the documentation, users should be able to look at the first few commented lines of future drivers to learn their purpose.

There are different terms that should be understood so that the information below is understandable. An I/O device is an Input/Output device.

OSS Leftovers

  • DataBasin - object inspector and updates
    First, the underlying DataBasinKit framework got an important update.
  • In-demand dev skills, understanding licensing, and more open source news
  • Higher ed systems expanding access to open-source materials
    Open-source learning technology is at the core of higher education for institutions that want to reach broader audiences with very strict ideas about how convenient learning should be. But developing these initiatives does not happen quickly or easily. It requires strong leadership in information technology, expertise to determine which solutions work best for a campus, and a financial commitment to making sure the technology is sustainable.
  • Proxmark Pro Proxmark3 Standalone Open Source RFID Tester (video)
    Rysc Corp has unveiled a new open source board in the form of the Proxmark Pro which now offers a true standalone client and RFID test instrument, check out the video below to learn more. The Proxmark Pro will feature an FPGA with 5 times the logic cells of the Proxmark3 and will remove the need to switch between HF and LF bit streams during operation, to use developers.
  • ErupteD Brings Vulkan To The D Programming Language
    The D programming language is just the latest to have support for Vulkan alongside C++, Rust (via Vulkano, if you missed that project), Go, and many other modern languages getting bindings for this Khronos Group high performance graphics API. Should you not be familiar with the D language, see Wikipedia.
